The central goal of this study was to characterize major patterns of reasoning exhibited by college chemistry students when analyzing and interpreting chemical data. Using a case study approach, we investigated how a representative student used chemical models to explain patterns in the data based on structure-property relationships. Our results…

First results from a 20-year survey of science knowledge and attitudes toward science among undergraduates are presented. Nearly 10,000 students taking astronomy as part of a general education requirement answered a set of questions that overlap a science literacy instrument administered to the general public by the National Science Foundation.…

Guided by a new framework, the NAEP science assessment was updated in 2009 to keep the content current with key developments in science, curriculum standards, assessments, and research. The 2009 framework organizes science content into three broad content areas. Physical science includes concepts related to properties and changes of matter, forms…

In 1994-95, an Arizona Math and Science Eisenhower Grant helped a Northern Arizona University-sponsored project train 20 K-12 Arizona science teachers in telecommunications applications and science curriculum integration. Preservice teachers also participated. Problems encountered were differences in teachers' workplace telecommunications…

The purpose of this document is to provide a framework for school districts to use in the development of K-12 science curricula. The framework focuses on those ideas, skills, and attitudes that have the greatest educational significance for enabling the achievement of scientific literacy by all students. The scope of the Arizona Science Essential…

This document represents the second revision of a similar guide (no longer in print) originally published in 1974. It was developed to help teachers in Arizona encourage students to: (1) become aware of human dependence on natural resources; (2) gain a fundamental understanding about our natural resources; (3) intelligently react to problems of…

The resource persons and program descriptions in this directory came from answers supplied in a 1988 survey mailed to 135 entities having some relationship to or interest in promoting the distribution of water education materials suitable for use in Texas elementary or secondary schools. This directory includes an update on the programs submitted…

In an effort to improve the science education program in the Washington School District (Phoenix, Arizona) the school system focused its efforts in the 1983-84 school year on the development of an activity oriented laboratory science program for grades 4-6. This document describes the plan for implementing that program. The implementation…
